exception occured when installing 6.1

[qwerasdfs yahoo, com mail redhat com]

Hi there,
Following execption occured during the installation of 6.1
File "/usr/bin/anaconda.rel"
 line 223 in ?
int.run(todo,test=test)
.....
......
/tmp/lib/python1.5/site-packages/harddrive.py 
 line 45
 /tmp/libpython1.5/site-packages/isys.py
    line 8
 return _isys.umount(what)
System Error(16,device or resource busy)
debugging fond what=/tmp/hdimage ( something like that )

I can install 5.x on the same machine without any problem.

I have only one hard drive and partioned it into 4 primary partions.
RehHat installed in hda4.

My installation packages are located at the same physical drive(hda, I
tried them in different paritons(hda1,hda4, hda6, but still the same).

It seems to me that, the installation programme try to unmount hda
while the packages are in one of its paritons that causes the problem.

According to the header of  harddrive.py, it is for NFS and CD where  packages
are located in drives different to the root file system. I was wondering
if the installation programme support installation from the same hard
disk ?

Using the latest updates boot and updates imgs have the same problem.



Can any body help ?
